Investigate the Mechanical properties of Al7075-MoS2 Composite via Powder Metallurgy

Abstract

Al7075 is a material that is both lightweight and has a high thermal conductivity. Aluminum is one of the best materials available, and it also happens to be one of the least expensive. This study examines the hardness, tensile strength, compressive strength, metallurgical characteristics, tribological behavior, impact of wear test parameters, and corrosion resistance of Al7075 hybrid composites reinforced with hard reinforcement MoS2. The powder metallurgy technique is used to create the Al7075 hybrid composites. Molybdenum disulfide served as a soft reinforcement to boost the corrosion resistance of the Al7075 hybrid composites and to give higher wear resistance with a reduced Coefficient of Friction. Al7075 hybrid composites contain 2%, 4%, 6%, and 8% weight of molybdenum disulfide. The scanning electron microscope is utilized to obtain SEM images in order to validate the homogeneous distribution of MoS2 within the aluminum 7075 matrix alloy. It is proof of a composite devoid of flaws and demonstrates the excellence of its fabrication.
